This year's QuakeCon will go heavy on the Doom, the famed FPS that preceded the big bring-your-own-computer show's namesake. The reason is that 2019 is, somewhat loosely, the 25th anniversary of the original Doom—it was released in December 1993—and Bethesda isn't going let the "Year of Doom" go uncelebrated.

QuakeCon 2019 "will include all-new Doom-inspired activities, events, exclusives, developer panels, hands-on demos, new information about Doom Eternal, and a few surprises we aren’t quite ready to talk about," Bethesda said. "All while continuing to feature everything you already love about QuakeCon."
